Data processing system capable of executing data processing using resources by designating displayed graphic patterns representing selected resources
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to a data processing system for displaying in the form of graphic patterns resources to be used in processing by the system. More particularly, the invention is concerned with an improvement of a user interface (man-machine interface) in a data processing system, such as a work station, high-performance personal computer and the like, appropriate for use in offices. 
     2. Description of the Prior Art 
     As a hitherto known means for facilitating interaction or communication between a user and a machine in a work station, a system has attracted attention in which resources usable by a user are taken for objects which are then displayed in terms of picture/character graphic patterns (hereinafter also referred to as the icon graphic pattern or simply as an icon or graphic pattern), wherein the user selects the objects to be used from the icons displayed, being followed by commanding a procedure to be executed using the selected object, to thereby proceed with the data processing. In this connection, reference may be made, for example, to an article entitled &#34;Technology for Implementing User Interface of Work Station&#34; in a Japanese publication &#34;Information Processing&#34;, Vol. 25, No. 2 (February 1984), pp. 103-110, published by &#34;Information Processing Society of Japan&#34;. 
     In the hitherto known system, however, the icon graphic patterns are inherently specific to the system and it was impossible to adopt the particular icon patterns in conformance with the environment in which the user works. Besides, in the hitherto known system, a plurality of names of displays can not be imparted to a single resource, differing from the case of logic names for a file, by way of example. 
     Such being the circumstances, when the prior art work station is to be applied to a multi-user environment in which one and the same apparatus or system is to be alternately used by a plurality of users, it is impossible to implement on the display unit the work environment optimum to each user, who is thus forced to use the ready-made icon graphic patterns and the resource display names. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide an improved user interface (man-machine interface) for a data processing system which can be used in a multi-user environment. 
     Another object of the present invention is to improve manipulatability of a data processing system which is capable of displaying graphic patterns corresponding to resources on a display screen and executing data processing by designating particular graphic patterns. 
     With a view to accomplishing the objects mentioned above, there is provided according to the present invention a data processing system for displaying resources, which are available for use in data processing in the form of graphic patterns, which system comprises first file means for storing resource identifying information to identify resources to be used in executing data processing by users in correspondence with user identifying information for identifying individual users, second file means for storing the graphic patterns and names thereof specific to each user in correspondence with each of the resources, display means including a screen capable of displaying a plurality of graphic patterns and names thereof, input means for inputting user identifying information in precedence to execution of data processing, control means responding to the inputting of the user identifying information for reading out the identifying information of the corresponding resources from the first file means while reading out the graphic patterns and the names thereof specific to the user and corresponding to aforementioned resources from the second file means to be outputted to the display means, and designating means for designating selectively one of plural graphic patterns or names thereof displayed by the display means, wherein data processing is performed using the resources corresponding to the designated graphic patterns or names. 
     According to the present invention, graphic patterns (icons) and names of resources are filed on a user-by-user basis so as to be retrievable with the aid of user identifying information (also referred to as user ID). At the beginning of operation of the work station, the aforementioned file can be retrieved by utilizing the user ID as a key code to thereby display the resources in terms of the graphic patterns and the names particular or proper to the user. In this way, the user can realize the work environment peculiar to him or her on the display screen. In other words, a work station which is easy to use can thus be implemented. Further, since information to be displayed is stored in the file, addition and alteration (such as updating and modification) of the information can be readily accomplished. 
     The foregoing and other objects, advantages, manner of operation and novel features of the present invention will be more fully understood from the following detailed description when read in connection with the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Now, the invention will be described in conjunction with exemplary embodiments thereof by reference to the accompanying drawings. 
     FIG. 1 shows a general arrangement of a work station for carrying out the present invention. In this figure, a reference numeral 101 denotes a data processing unit, 102 denotes a main memory, 103 denotes a mouse which constitutes a pointing input unit, 104 denotes a keyboard for inputting commands and data, 105 denotes a display unit such as a bit map display, 106 denotes a printer, and a numeral 107 denotes an auxiliary storage (e.g. memory disc). The memory disc 107 includes a program storing region (also referred to as the program file) 108, a user data file region 109, a profile (or attribute) information file region 110 for storing profile (or attribute) information of objects to be handled in the work station, an icon pattern data file region 111 for storing icon pattern data representative of the objects, and a user environment file region 112 for storing all the names of objects possibly used by individual users on a user identification (ID) basis. 
     FIG. 2 is a view for illustrating a variety of programs prepared in the program storage region 108 of the disc unit 107 as well as relationships therebetween. In FIG. 2, a reference numeral 201 denotes a job control program for controlling execution of various processing programs mentioned below, 202 denotes a program for performing a object moving/copying operation, 203 denotes a program for displaying in a list contents of an object when it is a directory, 204 denotes a program designed for registration (entry)/updating of the profile (attribute) information stored in the profile information file 110, 205 denotes an AP management program for loading APs (abbreviation of application programs) required for processing the object designated by the user, numerals 206, 207 and 208 denote a text editing program, a table processing program and a graphics editing program, respectively, which exemplify the AP programs, a numeral 209 denotes an object management program for establishing correspondence between objects and the profile information file 110 and performing input/output operation to and from the profile information file 110, and a reference numeral 210 denotes a kernel portion for providing system calls utilized when the object management program 209 makes access to the file system 211 
     Operations of the various programs will be considered below 
     The object management program 209 serves to ensure for all the file systems to be handled in the work station (each of which system is composed of a directory and a file) that the profile information file 110 storing the profile or attribute information concerning the object and the resource for storing the content of the object are always present to be available in a pair. In addition, the object management program 209 serves to back up the input/output operation to and from the profile information file 110. 
     FIG. 3 is a view illustrating the contents of the profile (attribute) information file 110. The profile information file is provided on an object basis and contains common information 310 concerning the object and user private information 311 which can be prepared by each user. The common information 310 includes, for example, an owner field 301 for the information about the owners of objects, a draw-up date field 302 for the information of the date when an object was prepared, a custody term field 303 for the information of custody term, a data format field 304 for the information about object data formats for identifying the application programs or APs required for processing objects, and others. On the other hand, the user private information 311 is adapted to be utilized for designating on a user basis such information as required for displaying the objects in terms of icons on the display screen 105 and includes items such as user identification (ID) 305, icon indication name 306, file name 307 of the file storing the graphics pattern of the icon, window display position 308, window size 309 and others. Unless the user private information 311 proper to the user has been registered, a common object name is used as the indication name of the icon, while data prepared previously by the system is utilized for the other items. 
     FIG. 4 is a view for illustrating relationships between the profile information file and directory. The profile information file of an object is linked to a parent directory to which the object is linked. By way of example, referring to FIG. 4, a profile information file (D-B) 403 of a directory (DIR-B) 402 is linked to a parent directory (DIR-A) 401, while profile information files (F-A) 404 and (F-B) 406 of files (FL-A) 405 and (FL-B) 407, respectively, are linked to a directory (DIR-B) 402. 
     FIG. 5 is a view for illustrating functions of the object management program 209. As is shown in this figure, the object management program 209 executes processings such as creation of an object (501), deletion thereof (502), movement of an object (507), copy of an object (508), reading of the profile information file (503), writing of the profile information file (504), updating of the profile information file (505), and collective reading of the profile information file (506). The processing of the user private information stored in the profile information file can be performed in such a manner that the user ID inputted at the start of operation of the work station by the user is utilized as key data for searching the user private information field 311 to obtain the user private information corresponding to the inputted ID. The names of the profile information files can be automatically made available by converting the sequence numbers attached to all the directories and the files constituting the file system to character strings through the kernel portion 210. 
     FIG. 6 illustrates in a flow chart the operation of the job control program 201 for carrying out the present invention. 
     At a step 601, the user ID is received which is inputted through the keyboard 104 upon starting operation of the work station by an operator. 
     At a step 602, the user environment file 112 stored in the disc 107 is retrieved with the user ID inputted at the step 601 being used as the key. 
     At a step 603, the object management program 209 is activated for the purpose of displaying the list of usable objects as obtained at the step 602 on the display 105 in terms of icons by reading out sequentially the user private information required for the display from the profile information file 110 for the objects in concern. 
     At a step 604, the icon pattern read out from the icon pattern data file 111 in accordance with the icon display name 306 and the icon pattern file name 307 for the object obtained at the step 603 is displayed on the display unit 105. Further, a list of commands accepted by the job control program 201 for the objects being displayed is also displayed on the display unit 105. 
     FIG. 7 shows an example of the image displayed at the aforementioned step 604. In the figure, a reference numeral 702 designates a displayed list of icons registered by the user and named &#34;Hitachi Taroh&#34;, and 701 designates a displayed list of commands received by the job control program 201. In the case of the illustrated example, the commands being displayed includes an object move command 703, an object copy command 704, a profile update command 705 for commanding the content updating for the object profile information file, a list display command 707 for displaying the members registered as the objects in a list, and an open command 706 for activating the AP for displaying the contents of the objects and processing the objects. An operator can designate the object and the command to be processed with the aid of the mouse 103. 
     As a step 605, the program for processing the command designated by the operator is activated. More specifically, the &#34;MOVE&#34; command 703 and the &#34;COPY&#34; command 704 activates the object moving/copying program 202. The &#34;PROFILE UPDATE&#34; command 705 activates the profile information file entry/update program 204. The &#34;OPEN&#34; command 706 activates the AP management program 205. The &#34;LIST DISPLAY&#34; command 707 activates the object list display program 203. 
     Upon manipulation of the work station following the registration of the user ID by the operator, the unwanted objects can be erased by moving them to a waste basket 708 under the &#34;MOVE&#34; command 707, since all types of objects are displayed at that time. Further, because the graphic patterns and the names of the icons are defaulted at this time point, it is necessary to designate the &#34;PROFILE UPDATE&#34; command 705 for updating individual profiles. 
     FIG. 8 illustrates in a flow chart the operation of the profile information file entry/update program 204. 
     At a step 801, the object management program 209 is activated, and the profile information of the designated object is read out from the profile information file 110. In that case, a profile information file input function 503 of the object management program 209 is made use of. 
     At a step 802, the profile information read out at the step 801 is displayed on the display unit 105 in an image format illustrated in FIG. 9 by way of example. 
     At a step 803, the operator is allowed to input the entry/update data of the profile information. 
     At a step 804, the object management program 209 is activated to write the registered and updated profile information into the profile information file. In this case, a profile information file creating function 504 and a profile information file updating function 505 are made use of. 
     FIG. 10 is a view showing that different graphic displays can be generated in dependence on the difference of the user private information, as an example for illustrating the operation of the object list display program 203. More specifically, the object list display program 203 is designed to display in terms of icons a list of those objects registered at the designated objects (in this case, the objects are limited to the directories of the file system). To this end, the collective profile information file inputting function 506 of the object management program 209 is made use of. 
     An example of the operation illustrated in FIG. 10 will be described in conjunction with the file system shown in FIG. 4. Referring to FIG. 4, it is assumed that the directory 402 has registered therein two files 405 and 407. For this directory 402, the user A sets to his or her private information 1011 stored in the profile information file 403 the information of an icon graphic pattern 1002 shown in an object list 1001 of an image 1003 being displayed, the display name &#34;CABINET&#34; 1009 and the information about the position and size of the cabinet window for displaying a list of the contents of the directory 402. 
     On the other hand, a user B places in his or her private information 1012 stored in the profile information file 403 the information about an icon graphic pattern 1006 shown in the object list 1005 of the image 1007 being displayed, the display name &#34;DOCUMENT CASE&#34; and the position and size of a document-case window 1008 for displaying the list of contents of the directory 402. Further, the users A and B set to respective profile information files 404 and 406 the information of respective icon graphic patterns and names to be displayed. As will now be appreciated from the above description, the image 1003 is displayed in the case of manipulation by the user A, while the image 1007 is displayed for the user B. In this connection, it should be mentioned that in the case of manipulation by a user whose private information is not set, the actual name (e.g. DIR-B) of the object is utilized as the name of display, while graphic patterns of defaults determined for all types of the objects such as the directories and files are utilized as the patterns to be displayed. 
     With the system illustrated above, there can be provided an easy and familiar man-machine interface because the user can display the objects in terms of logical names and preferred graphic patterns such as a cabinet, a minute book and so forth in place of the actual names of the objects such as DIR-A, FL-A and so forth. 
     The object move/copy program 202 shown in FIG. 2 executes the movement and copying of the object by making use of a moving function 507 and a copying function 508 of the object management program 209. When the destination to which an object is to be moved is the &#34;WASTE BASKET&#34; 708, a deleting function 502 of the object management program 209 is made use of for deleting the destination. 
     FIG. 11 illustrates in a flow chart operation performed by the AP management program 205. 
     At a step 1101, the object management program 209 is activated to thereby allow the profile information of an designated object to be read out from the profile information file. In this case, a profile information reading function 503 of the object management program 209 is utilized. 
     At a step 1102, the content of the designated object is inputted with the aid of the system call provided by the kernel portion 210 to be thereby displayed on the display unit 105 in accordance with the information about the window display position 308 and the window size 309 contained in the profile information read out at the step 1101. 
     At a step 1103, the AP corresponding to the data format 304 contained in the profile information read out at a step 1101 is loaded to thereby initiate the processing for the designated object. More specifically, when the data format 304 is table data, a table processing program 207 is loaded while the text editing program 206 is loaded when the data format 304 is the text data, whereby the processing is initiated. 
     As will be appreciated from the foregoing description, it is possible according to the teachings of the present invention to set in an arbitrary manner the graphic patterns of icons representative of objects, the names thereof and the display position to be processed by the work stations. Accordingly, when one and the same apparatus is used in common by a plurality of users, each user can derive the optimum icon display conforming to the environment in which the apparatus is employed.
